S900 is a remote I/O family designed for applications with hazardous-rated areas according to ATEX. The I/O system can be safely located directly in ATEX Zone 1 and 2, saving wiring and signal conditioning costs. To download a PDF OUTLINE of all modules in this section, or to COMPARE several items, use the options in the upper‑right corner of the page.
S900 I/O incorporates complete redundant networking capability, including redundancy
in power supply, communication interface, and PROFIBUS DP connection.
The main areas of application are the chemical industry, the pharmaceutical industry, and the
oil and gas industry. Throughout its proven track record and wide temperature range and coating,
the S900 I/O has been used in many areas where durable and long-standing equipment is needed.
Extended diagnostic functions and the use of HART®-compliant field devices in the Fieldbus
system reduce the maintenance effort and therefore, lead to savings throughout the service life of the plant.
